Title: Detector for wire breaking of tachometer generator
Inventor: TAMURA YASUHARU
IPC: H02K11/00
Filed: 1983-06-13
Abstract: PURPOSE:To detect securely the breaking of wire of a tachometer generator by outputting a wire breaking detection signal on the basis of the results of detection for detecting a voltage higher than a specific value being applied to a DC motor, and detection for the output voltage of the tachometer generator being smaller than a specific value. CONSTITUTION:When the DC motor 2 rotates, the tachometer generator 3 outputs a voltage proportional to its rotation, and the output of an operational amplifier 12 goes down to a low level when the output voltage exceeds the voltage division value of resistances R4 and R5. On the other hand, when the output volt age of the generator 3 exceeds the negative voltage division value of resistances R6 and R7, the output of an operational amplifier 13 goes down to a low level; when the voltage proportional to the driving voltage applied to an operational amplifier 11 exceeds the voltage division voltage of resistances R3 and R4, the output of the operational amplifier 11 goes up to a high level. Therefore, when the driving voltage is applied to rotate the motor 2 and the output of the generator 3 within a specific range goes down almost to 0V, a tri-input AND element 14 outputs the wire breaking high-level signal of the generator 3, and the breaking of wire of the tachometer generator is detected securely without recognizing erroneously that the low-speed rotation of the motor 2 is the breaking of wire.

Title: Cooling drum for casting thin billet
Inventor: FURUYA TAKASHI
IPC: B22D11/06
Filed: 1989-04-24
Abstract: PURPOSE:To produce a thin billet having excellent surface characteristic by packing recessed parts formed on peripheral surface of a cooling drum with refractory to form a smooth surface. CONSTITUTION:The plural recessed parts 2 are formed on the peripheral surface of the cooling drum 1, and at the time of bringing the peripheral surface of the cooling drum 1 into contact with the molten metal, the recessed parts 2 form independent air gaps, which are not mutually connected. Therefore, cooling condition of the solidified shell growing on the peripheral surface in the cooling drum 1 is released to avoid the concentration of stress in a part, which locally has low rigidity. The refractory 6 is packed into the recessed part 2 and the peripheral surface in the cooling drum 1 is smoothly finished. Therefore, the contacting condition between the peripheral surface in the drum 1 and the molten metal, is made to uniform to the drum axial direction and rotational direction and it is unnecessary to give the molten metal vibration. By this method, the molten metal surface in pouring basin part is held to still and the solidification of the molten metal 4 and the growth of the solidified shell are executed under the stable condition and the obtd. thin billet is prevented from the generation of traverse wrinkle.

Title: Printed-wiring board
Inventor: KAJIURA SADAO
IPC: H05K1/03
Filed: 1994-05-19
Abstract: PURPOSE:To obtain a printed-wiring board whose dielectric characteristic and mechanical strength are enhanced by providing a fiber-cloth base material in which a filament having a plurality of hollow parts which are independent of each other in the length direction is contained as a main material. CONSTITUTION:A fiber-cloth base material 3 is formed of a woven cloth composed of a filament 10 in which a plurality of cylindrical hollow parts 9 are arranged in a row so as to be independent of each other in the length direction. When it is formed in this manner, its permittivity and its dielectric loss tangent can be reduced. In addition, since bulk parts are formed between the respective hollow parts 9 in the fiber-cloth base material, the mechanical strength of a printed-wiring board can be enhanced. In addition, since the hollow parts 9 are independent of each other, the inside of every hole formed by a drilling operation is hard to notch in a drilling process, and a drilling property can be enhanced.

Title: Thyristor
IPC: H01L29/749
Filed: 1992-03-31
Abstract: PURPOSE:To form a thyristor having high turn-OFF capacity by inhibiting to operate a parasitic transistor due to a hole current in an element in the case of turning OFF. CONSTITUTION:In the case of turning OFF, a positive voltage to a cathode voltage is applied to a gate terminal G1. Then, a p-type channel formed on an n-type layer 6 is vanished, and supply of electrons from a floating electrode 11 to an n-type emitter layer 5 is stopped. As a result, no base current flows to a transistor formed of an n-type base layer 3, a p-type base layer 4 and the layer 5 to turn it OFF. Since the layer 6 is not connected to a cathode electrode 8, a parasitic transistor or a parasitic thyristor does not exist. Since the parasitic transistor, thyristor are not operated by the hole current in the element, a GTO thyristor having a high turn-OFF capacity can be formed.

Title: Surface treatment of thin metallic film
Inventor: MATSUDA HIROMU
IPC: G11B5/64
Filed: 1982-06-18
Abstract: PURPOSE:To provide high corrosion resistance to the surface of thin metallic film by a simple method by subjecting the surface of the thin metallic film to a contact treatment with a rust preventive agent then polishing the treated surface with a polishing material. CONSTITUTION:The surface of the thin metallic film formed of Fe, Co, Ni, Cu or their alloy, etc. as a material is subjected to a contact treatment in a liquid phase or vapor phase with a rust preventive agent to stick the rust preventive agent on the surface. The treated layer stuck on the metallic surface by the contact treatment is polished with a polishing material. The rust preventive agent in the part where said agent is excessively stuck is removed by the polishing treatment, and part thereof is stuck on the surface in the part where the rust preventive agent is not stuck; at the same time, said agent is made extremely thin and uniform by the polishing effect. As a result, excellent rust preventive and corrosion preventive effects are obtained without spoiling the various characteristics intrinsic to the thin metallic film. Compds. of triazole, imidazole and thiazole types are used for the rust preventive agent.

Title: Production of unsaturated polyester resin composition
Inventor: YAMADA MASAE
IPC: C08L67/00
Filed: 1985-05-20
Abstract: PURPOSE:To obtain a resin compsn. which has excellent wear resistance and gives moldings having an excellent appearance, by adding additives and a fibrous polyethylene to a resin and kneading the mixture with heating. CONSTITUTION:50-500pts.wt. filler and other additives and 1-35pts.wt. fibrous polyethylene having a diameter of 20mu or below and a m.p. of 130-135 deg.C are added to 100pts.wt. resin and the mixture is kneaded at 120-140 deg.C. The gist of this method resides in polyethylene to be used and heat kneading conditions. When the m.p. of polyethylene is lower than 130 deg.C, only an effect of improving wear resistance due to a lubricating effect on the surface of a molding can be obtd. Thus, it is considered that the molding is excellent in wear resistance at the early stage of wearing. However, after the skin layer on the surface of the molding is lost as wearing proceeds, wearing is rapidly increased. When the kneading temp. is lower than 120 deg.C, polyethylene is not sufficiently molten, while when the temp. exceeds 140 deg.C, the curing reaction of the unsaturated polyester resin proceeds and hence stable kneading is not possible.

Title: Synchronous controller for motor driven machine
Inventor: GOSHI TADAO
IPC: H02P5/52
Filed: 1986-05-09
Abstract: PURPOSE:To rapidly automate the synchronous operations of a plurality of motor driven machines by switching to the control of speed coincidence at the end of the control of position coincidence. CONSTITUTION:When a mechanical position displacement occurs at a tray and a conveyor at the operation starting time, the output of a PLL circuit 115 is applied through a contact 113 as a correction signal, and the output frequency of a power source 8 is increased or decreased in a direction that mechanical positions coincide. As the displacement of the mechanical position due to the increase or decrease is reduced, the output level of the PLL circuit 115 drops. When it reduces lower than the comparison reference level of a comparator 116 due to the coincidence of the mechanical positions, a relay 114 is energized by the inversion output to a comparator 116 to close the contact 112 and to open the contact 113. Thus, it enters the speed coincidence control by a PLL circuit 111, power sources 7, 8 thereafter operate in the same phase at the same speed to synchronously operate the conveyor and the tray.

Abstract: PURPOSE:To improve a shearing strength, and to eliminate peeling of a metal layer from a semiconductor device by providing a coupling metal for coupling upper and lower metal layers, and covering the outer peripheries of the upper and lower layers with insulating films. CONSTITUTION:Bonding pads 26 are formed of first and second metal layers 22, 23, and a coupling metal 25 for coupling the layer 22 to the layer 23 on a semiconductor substrate 21. The outer periphery of the layer 22 is covered with an interlayer insulating film 28 together with the substrate 21 therearound and a metal interconnection pattern 27. Accordingly, the layer 22 is pressed to the substrate 21 by the film 28 covering the outer periphery. The metal 25 is formed in contact with the layer 22 not covered with the film 28. Accordingly, the outer periphery of the layer 22 protrudes to the side from the junction of the metal 25. The layer 23 is covered with a passivation film 30 together with the film 28 at the outer periphery. Therefore, the layer 23 is pressed to the substrate 21 by the film 30 covering the outer periphery.

IPC: H02P23/00
Filed: 1998-04-02
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive simple PWM system which can completely correct the distortion caused by dead time when an inverter feeding inductive load is driven. SOLUTION: A PWM system 100 incorporates an inexpensive voltage sensor 140 which detects the output voltage of the system at the end of each continuous dead time period in which neither a pull-up transistor 51 nor a pull-down transistor 52 are driven. The system 100 also incorporates a programmable PWM 125, two storage elements 131 and 132 such as D-type flip flops, etc., and a memory-mapped register 133. The register 133 stores the outputs of the flip flops and shows a nearly-zero load current state. When this state is detected, the system 100 generates an output voltage and an output current which more closely approximate a sine wave by changing the duty cycle of the output signal of the PWM 125. The system 100 is particularly useful as part of an inexpensive microcontroller 120.
